The words "Michael Jackson" and "sued" these days tend to be rather synonymous.
This time Jackson is being sued, as opposed to suing. His one time friend, Prince Abdullah of Bahrain, is taking Jackson to court.
Prince Abdullah took Jackson and his family in after the 2005 child molestation trial. Having looked after Jackson and entourage, the Prince wanted to start a record company with the King of Pop.
Various agreements were signed, then nothing happened. The Prince is now fed up with this inactivity and is suing Jackson to honour the agreement and to do some work, eg make a record.
The case is being brought in London.
